Need Help turning on Car

[Omi 0]

Need help turning on a 91 MR2 3sgte with coils and other aftermarket parts.When I crank the engine it backfire. I check the timing with a timing gun and it's on time.Car sparks and has fuel pressure. Going to attach the map that I am running on the car.

Are you 360 degrees out ?

The other trigger offset number that was on 0 was  -240 but I didn't try it with the fuel on. That one of the things I am going to try tomorrow

It turned on -243 but knock level stays on 1000 knock counter stays on 250 using oem knock sensor.Is it supposed to be in those numbers

Drop the gain down, adjust the knock target so it’s just above the noise.

I did what you said and numbers went down.I have question vacuum or map reading is around 10 at idle is it to low.

10 kpa  MAP or -10 MGP (ie 90kpa)?

10kpa would be very low, typically you would only see this amount of vacuum on overrun and i'd be suspicious of your MAP calibtraion if you see this at idle.

90kpa (ie -10 MGP) is very high for a factory intake manifold and cams. You might see this with ITB's and big cams, but factory cams and manifold should give you 25-40 MAP (ie -60 to about -75 MGP) and 90kpa would suggest an intake leak or again, MAP calibration issues.

10 psi MAP and -4.6 psi MGP.I do have bigger cams and factory intake manifold.

so about 65-70 kpa. with bigger cams its a believable number. If you're suspicious or have unstable idle then a smoke/leak test wouldnt hurt, but its in the ballpark assuming a fair bit of cam overlap.
